Ductwork Built To Actually Cool Your Home.

Old, undersized, or leaky ductwork is one of the biggest reasons a perfectly good AC still can't keep a house comfortable. We design and install properly sized duct systems that move the right amount of air to every room — no more hot spots, no more guessing.

Don't Ignore These

Signs Your Ductwork
Needs Replacing

Ductwork wears out quietly, long before your AC does. If any of these sound familiar, it's worth a free estimate.

Leaky or Disconnected Ducts
Gaps, crushed sections, or disconnected joints let cooled air escape into the attic before it ever reaches a vent.
Uneven Room Temperatures
Undersized or poorly routed ducts mean some rooms never get the airflow they need, no matter the thermostat setting.
Ducts Older Than Your System
A new AC connected to 20-year-old ductwork is still limited by the ducts — it can only deliver what the system will move.
Damage or Pest Intrusion
Chewed, torn, or crushed ductwork in an attic or crawlspace can't be patched forever — at some point it needs replacing.
The Difference Is Real

What Proper Ductwork
Actually Changes

30%
The U.S. Department of Energy estimates that homes can lose up to 30% of conditioned air through leaky, poorly sealed, or undersized ductwork before it ever reaches a vent.

Figures reflect typical performance gaps between aging, leaky ductwork and a properly sized, sealed installation, based on U.S. Department of Energy duct-loss estimates. Actual results vary by home.

How It Works

Our 5-Step
Installation Process

Every install follows the same sequence, in this order, so the finished system is sized right and sealed tight.

Step 1
Load Calculation
A room-by-room Manual D calculation determines the right duct size and layout for your home.
Step 2
Design & Layout
We map the shortest, most efficient duct runs to cut down on air loss and noise.
Step 3
Remove Old Ductwork
Existing ducts are removed and disposed of where a full replacement is needed.
Step 4
Install & Seal
New ductwork is installed, supported, and sealed at every joint to stop air loss at the source.
Step 5
Airflow Testing
We measure airflow at every register and walk you through the results before we call it done.

Why Sizing Matters Here

Built for the
Las Vegas Heat Load

A duct system sized for a mild climate falls apart in a Las Vegas summer. Attics here regularly top 140°F, and an undersized or leaky duct run loses conditioned air fast before it ever reaches a room. Correct sizing and sealing isn't optional in this heat — it's what determines whether your AC can actually keep up.

Extreme attic temperatures make duct sealing and insulation critical, not optional.
New construction and additions need ductwork sized for the home, not a generic template.
A right-sized system runs longer, gentler cycles instead of straining through short bursts.

Common Questions

Duct Installation
FAQ

How long does a full duct installation take?
Most single-family homes take 1–2 days for a full duct replacement, depending on square footage, attic access, and how many supply and return runs are involved.
Do you handle new construction and additions, not just replacements?
Yes. We design and install ductwork for new builds, room additions, and full system replacements — each one sized to the space with its own load calculation.
What kind of ductwork do you install?
We work with sheet metal and insulated flex duct depending on the application, and select the right material for each run based on space, airflow needs, and budget.
Do I need a permit for duct replacement?
Many duct installation and replacement jobs in the Las Vegas valley require a permit. We handle the permitting process as part of the job so you don't have to.
